Life Cycle Assessment of Wood Hemicellulosic Bio-ethanol Rachel
Bowman Western Kentucky University, Massachusetts Institute of
Technology Advisor: Dr. Anthony Halog Cradle to Gate LCA of wood
based bioethanol using SimaPro, Eco-LCA, Open LCA models Considers
Near-Neutral extraction method of producing hemicellulosic bio-
ethanol as part of a modified Kraft Pulp Mill Compares the three
LCA models and determines which presents the best representation of
the data Preliminary SimaPro results show that the greatest
environmental impact categories are Fossil Fuels, Respective
Inorganics, Climate Change, Land Use, and Acidification from the
Causticizing Process, Wood Chip Production, and Hog Fuel Boiler
Normalized Environmental Impacts from Ethanol Production

Hydrodeoxygenation of a Model Compound of Pyrolysis Oil Using
Molybdenum Catalysts on Activated Carbon Supports. Nick Dunn Union
College. Advisors: Dr. Brian Frederick and Dr. Clayton Wheeler 0.5g
of the sulfided catalyst is added to 3.00mL of the model compound
guaiacol in 100mL decalin. The mixture is heated up to 300C and put
under 50 bar H 2 pressure for 4 hrs, with periodic samples
taken
Slide 6
Converting Lignin into Nano Structured Carbon Materials Alden
Earle Ramapo College of New Jersey Advisor: Dr. David Neivandt
Lignin is an underused byproduct of the Kraft pulping process that
is largely burnt for fuel. It is the 2 nd most plentiful organic
polymer in the world. Nano-carbon is used for numerous applications
due to its high electrical and thermal conductivity, high tensile
strength, surface area etc. However, it is typically expensive to
mass produce and employs non-renewable feedstocks. A proprietary
method of converting lignin into nano structured carbon materials
is being developed. Significant room exists for optimization of the
process.

Utilizing Tangential Flow Ultrafiltration for the Concentration
of Hemicellulose Extracts Rob Jonson Kansas State University
Advisor: Dr. Peter van Walsum & Graduate Student Sara Walton
Hot water and green liquor hemicellulose extracts must be
concentrated before they can be fermented. Filtration might be
optimized by developing a relationship between extraction intensity
and the extracts molecular weight distribution.

metabolites found in bark by liquid-liquid extractions
Classification based on antioxidant activity, phenolics, and
flavonoids content Effort to use most environmentally-conscious
solvents

Bioprospecting for an enzyme that cleaves ether bonds between
lignin and hemicellulose in hardwoods Rosie Ochoa- Sacramento City
College Advisors: Dr. Nancy G. Kravit Environmental colonies
Environmental samples and ATCC cultures were screened for their
ability to cleave the ether bond between xylan (primary sugar in
hardwood hemicellulose) and 4- Methylumbelliferone. Positive
cultures were grown and tested in different media and growth
conditions to optimize enzyme expression.
Slide 11
Acid springing and extraction using trioctylamine Audrey
Polifka Kansas State University Advisor Dr. Peter van Walsum Goal
is to extract acetic acid from a model solution using trioctylamine
(TOA) as the extractor and octanol as the diluent. Testing
variables such as concentrations of organic & aqueous phases,
ratio of organic to aqueous, temperature of reaction, and pH of
aqueous phase. Also determining recyclability of TOA to be used in
economic analysis.

HS Student: Mark Rowe Goal: Minimize tree waste in an optimized
industrial ready process that maximizes yield of shikimic acid at a
low cost while maintaining other industrial operations at their
current capacity. Initial Findings: Higher temperature = Better

Isolating a Novel Enzyme that Cleaves Non- glycosidic Bonds
Between Lignin and Hemicellulose Morgan Urello Columbia University
Advisor: Dr. Nancy Kravit & Dr. Kathy Schmidt B603 produces an
enzyme that cleaves the non-glycosidic bonds between lignin and
hemicellulose cDNA from B603 has been used to create a lambda
library The library was screened using a substrate that mimics the
lignin-hemicellulose ether bond The insert coding for the desired
enzyme is being identified and subcloned into an expression vector
to optimize production Figure 1. Plaque Lift membrane under 254 nm
